Side hull window thickness?

The side windows on my Pahi 42 are not in the best shape... I guess no need for immediate replacement, but sooner or later it will be necessary.

They appear to have been made from 10mm (cast?) acrylic or so, which is also what I found recommended on some general boat forums.

However, I found some pretty good 5mm extruded acrylic sheets here in the local hardware store for a good price and to me at least they seem pretty strong.

Anyone has recommendations or experience with such thinner acrylic windows? 5mm is probably the minimum that can be used?

I also noticed that the current cockpit pod windows are already made with a thinner acrylic...8mm probably. Is the general idea that these windows need to be less strong than those on the main hulls?
